This post provides the details of a vulnerability in a WordPress plugin not discovered by us, where the discoverer hadn’t provided the details needed for us to confirm the vulnerability while we were adding it to the data set for our service, so its contents are limited to customers of that service. If you are not currently a customer, you can sign up for free here and then you can view the contents of the post. There are a lot of other reason that you will want to sign up beyond access to posts like this one, including that you would have already been warned about this vulnerability if your website was vulnerable due to it.
